These messages are disguised as system alerts, creating the illusion that the device is infected with malware.

However, there is a more serious scenario when the phone is actually installed adware an advertising application that penetrates the system through third parties stores or downloaded apk files. In this article, we will analyze in detail the algorithm for cleaning your browser from spam, blocking malicious scripts and completely removing hidden threats that interfere with the comfortable use of the Internet.

Disabling notifications from suspicious sites

The most common reason that the screen of your smartphone is suddenly filled with advertisements for casinos or weather forecasts is an active subscription to notifications from unverified resources. The browser perceives this as a legitimate user request, so standard antivirus apps may not respond to such actions. To stop this flow, you need to manually check the list of allowed senders in the settings.

Go to the main browser menu by clicking on the three horizontal bars at the bottom of the screen (or at the top, depending on the interface version). Go to section Settings, then find item Sites or Advanced. Here you should be interested in the subsection Notifications. In the list that opens, you will see all the resources that are allowed to send messages.

Carefully study the list of domains. If you see unfamiliar names or sites with suspicious addresses, click on them and select the option Block or Delete. Feel free to turn off notifications even from familiar news portals if they send too much spam. This action will instantly stop pop-ups from these sources.

  • 🚫 Never click the “Allow” button on sites with questionable content or aggressive advertising.
  • 🔍 Regularly check the list of permissions, as new sites can be added there automatically with an accidental click.
  • ⚙️ Use the "Turbo" mode or the built-in ad blocker to prevent downloading of malicious scripts.

It is worth noting that mobile application interfaces are frequently updated, and the location of menu items may change slightly. If you do not find the exact name of the section, look for synonyms like “Content”, “Confidentiality” or “Site Permissions”.

⚠️ Attention: If, after disabling notifications, advertising continues to appear on top of all windows, it is possible that a third-party virus application is installed on your phone, and not just a site spamming through the browser.

Clearing cache and data browser

Sometimes malicious scripts are not saved as active notifications, but end up in the browser cache, causing redirects or replacing content on visited pages. Standard cleaning of browsing history often does not affect system cache files, where temporary data that triggers pop-ups may be hidden.

For deep cleaning, go to the system settings of your smartphone Android. Find the section Applications or Application Manager. In the list of installed apps, find Yandex Browser and open its properties. Here you will need the tab Storage or Memory.

Press the button Clear cache. This is a secure operation that will delete temporary files but keep your bookmarks and passwords. If the problem is not solved, you can use a more radical method - button Reset or Clear data. Be careful: this action will return the browser to its factory state, deleting history, saved logins and settings.

Search and remove hidden advertising applications

If clearing the browser settings did not help, and pop-up windows appear even on the desktop or in other apps, This means that a malicious application has settled on your device. The trick with modern viruses like adware is that they are often disguised: they may not have an icon in the menu, or they call themselves system processes like “Update Service” or “Flash Player.”

Check the list of all installed applications in your phone settings. Look carefully at the installation dates - if you see a app that was installed around the same time that the advertising started, this is a suspicious sign. Try to remove all incomprehensible utilities, especially those that do not have an icon or name.

Pay special attention to applications with rights "On top of other windows". It is this permission that allows advertising to block the interface of the browser and other apps. Go to Settings -> Applications -> Special features (or Advanced settings) -> On top of other applications. Revoke this permission from all suspicious apps.

Do not rely only on visual inspection. Malware may be hidden under the names of system services. If you doubt the legitimacy of the app, enter its name into a search engine from another device before. deletion.

Configuring built-in protection and blockers

Yandex Browser has powerful built-in security tools, which by default may not be configured as strictly as possible. Activating the function AdGuard or similar modules inside the browser allows you to filter traffic even before the advertising code is executed on the page.

In the browser settings menu, find the section Security. Make sure that the switch Blocking ads and shocking ads is active. It is also recommended to enable protection against fraudulent sites and downloading files only from trusted sources.

To enhance protection, you can install third-party DNS filters. This does not require installing additional applications, but works at the system level. In the Android network settings (private DNS), you can specify a blocker address that will block advertising domains for all applications, including the browser.

  • 🛡️ Enable Incognito mode to visit sites with a dubious reputation.
  • 📵 Disable JavaScript for specific sites in advanced settings if they abuse pop-ups.
  • 🔄 Regularly update your browser via Google Play to receive the latest databases of malicious sites.

Reset network and DNS settings

In rare cases, the problem of pop-ups is associated with a change in the DNS settings at the level of your provider or the Wi-Fi router to which the phone is connected. If redirects only occur when using a specific Wi-Fi network, the problem may not be with the phone, but with the router that has been compromised.

Try switching to mobile data and checking if the problem persists. If the ads have disappeared on mobile data, reset your home router to factory settings. On the smartphone itself, you can reset the network settings: this will delete saved Wi-Fi passwords and Bluetooth settings, but return the network protocols to their original state.

To do this, go to Settings -> System -> Reset settings -> Reset Wi-Fi, mobile data and Bluetooth settings. Confirm the action. After rebooting, reconnect to the network and check the browser.

⚠️ Attention: Resetting network settings will delete all saved passwords for Wi-Fi networks. Make sure you remember your home Internet access details before performing this procedure.

Extreme measures: hard reset of the device

If none of the above methods helped get rid of annoying ads, and they continue to appear even after removing all suspicious applications, it is possible that malware has embedded itself deep into the system or has acquired device administrator rights.

In such a situation, the only guaranteed solution is to completely reset the smartphone to factory settings (Factory Reset). Before doing this, be sure to create a backup copy of important contacts, photos and documents, since all information from the internal memory will be permanently deleted.

The procedure is performed through the menu Settings -> Restore and reset -> Data reset. After rebooting, the phone will be as clean as it came from the store. During the initial setup, do not restore applications from an old backup immediately, but install them manually so as not to return the virus back.

Frequently asked questions (FAQ)

Why do ads appear even if I have not visited suspicious sites?

Ads may appear due to the fact that you previously accidentally allowed notifications to a legitimate site that was later hacked or began selling advertising space to spammers. It is also possible that there is a hidden miner application or an advertising module in a free game.

Can an antivirus remove pop-up windows in the browser?

Yes, modern mobile antiviruses (for example, Dr.Web or Kaspersky) have modules for searching for adware and blocking phishing sites. However, they cannot always revoke permissions for notifications manually granted by the user - this must be done in the browser settings.

Is it safe to use third-party ad blockers?

Using proven blockers (for example, AdGuard) is safe and effective. However, avoid downloading “super cleaners” and “boosters” from unknown sources, as they are often the source of advertising and viruses.

What to do if the “Delete” button for an application is inactive?

This means that the application has device administrator rights. Go to Settings -> Security -> Device administrators, uncheck the suspicious application, and only then try to remove it again.
